To all whom it may concern:

Be it known that l, CHARLns FREDERI K VVAGNER, a subject of His Majesty the King of lilmgland, residing at 3 1 Tollington Place, Finsbury Park, in the county of London,

Kingdom of England, have invented certain.

new and useful Improvements in Shears Especially Applicable for Hedge-Cutting and the like, of which the following is a specification.

This invention relates to manually or power driven shears for hedge cutting and the like of the kind in which a pair of cutting plates are employed; one of the plates being fixed, the other being removably 'secured androtatably mountedover the said fixed-plate to cooperate therewith to produce a shearing action. Heretofore it has been proposed to construct such shears with a suitable arm carrying the fixed cutting plate at its forward end, a crank handle and tooth with a spur wheel on the end of the arm to cause the rotating cutterplate to revolve, a

hand grip formed on said arm'intermediate of its ends and a rest at the rear end of the arm. It has also been proposed in the construction of a revolving cutter torc-lipping and shearing apparatus to mount separately or in groups, a number of radially arranged blades upon a central disk or plate by means I of screws.

Now the present invention which consists in the'improved construction, arrangement, and combination of parts hereinafter pointed out in the claim is chiefly distinguished from other devices. of the kind in the con struction of the fixed cutter in two parts and also in the provision of a pivotally mounted rest on the end of the arm of the device.

Referring to the accompanying drawings, Figure 1 is a plan View of the device; Fig.

2 is an elevation thereof, and Figs. 8, 4c and 5 show modified forms of blades. v

According to my invention 1 form the fixed cutter in two parts as shown in Figs. 3 and 4, and I provide a plurality of teeth or blades a on each part by removing therefrom a. number of sector and V-shaped pieces I) and 0 respectively. These teeth are suitably tapered and sharpened on one side to form cutting edges d. Onepart of the fixed bladesthus formed are attached to a suitable arm or handle 6 one end of which is jointed at f to turn either bac ward or foras to produce a shearing action ward, so that its end 'f can abut against the -handle 6 and enable it to beheld firmly against the body or shoulder of the operator,

the said arm being also pr'ovided, with. a

sepa'rateffhandle: g about midway of its length for the purpose of enabling the shears to be held firmly'when in operation Actcutting edges e disposed in relation to the cutting edges of the fixed teeth orblades so blades k are rotated. v

The plate or disk carrying the blades h" is provided with a chain wheel or pulley]:

and is adapted to be driven through the medium of a chain, belt, or cord j froma second chain wheel or pulley lmounted on any suitable part of the arm so as to be turned by means of a crank handle or the like m. I could also provide-additional chain wheels or pulleys of various diameters on the disk and handle so that the speed could be variedby moving the fchain or belt when the it $1ieeifioationof Letters Patent. 7 3a,:a'gn15, 'npgilicationnledmarchgi,19M. terminate from one pair of chain wheels or pulleys to the other. In place of the chain 3', I might also employ acord: or belt'and with such an. arrangement that it would then be possible to twist the-belt .so that the-wheelscorresponding to those hand Z would be disposed in planes at right angles to one another with the cutter blades then horizontal.

' The cutter shown in Figs. 3 and 4 are as before described made in two parts 'n, a

which are adapted to be secured together by screws or the like passing through holes p, while the rotating blades 9 may if desired be separately attached to a central. plate as shown in Fig. 5,'instead of being made in one piece as in Fig. 1. 4

a My improved shears are especially suit able for cutting the top and sides of a hedge and this can be done at a much greater speed than with the hand shears or other devices at present generally used for this purpose.

If desired the arm or handle could be made of considerable length so as to reach trees or high hedges or other normally inaccessible places.

What I claim as my invention and desire to secure by Letters Patent of the United States is A hedge trimmer of the character described, comprising a handle, a blade plate fixed thereto, said plate comprising twosemi-circular members, one of the said members having a depressed portion at its center, the other member having a central portion fitting within the said depression and hav- 'ing radiating cutter blades, the upper surfaces of the said members being flush and in .the same plane, means adjacent their centers for holding the said blades together, a stub I shaft carried by the said blade plate, a revplate and sprocket carried of radiating cutter blades and asprocket Wheel on the handle, a sprocket chain passing around the two sprocket Wheels, a crank on the second sprocket Wheel, a hand grip on the handle and a pivoted rest on the said handle, the

parts arranged as and for the purpose described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
